I have nearly 20 missed calls from this number and they never leave a message. I finally answered it today and a man's voice said "I'm looking for" and then my sister's name. The guy's voice sounded monotone (possibly a recording) and it didn't sound very friendly so I hung up. My guess is it's some sort of scam or telemarketer, cause if they're not willing to leave a message after that many calls, then that's usually a warning sign that you shouldn't call back.
